Object renders black
You simply imported the mesh, and that is it. You have no lights in your scene. You (kind of) need a light to see your object. You also could use an hdr, but that is just complicating things unnecessarily.

For just a simple test render, or so you can see your object, a three point light setup will work (and make Gleb Alexandrov cringe).  



You also need to turn off Auto Smooth for your object. There is something about the bad mesh (probably has to do with the normals) that is making auto smooth break.
Auto Smooth is found in the mesh tab of the properties window.


After the two changes I listed above, I rendered out your object like this.
